However, general methods to measure protein concentration of protein\u2013particle solutions are lacking. Typically, proteins in turbid solutions require separation or staining with another chromophore to quantitate their concentration. Here we demonstrate a label-free, direct approach to measure protein concentrations in turbid solutions using a UV\u2013vis integrating cavity absorbance spectrometer. Three systems are used to test the ability to measure accurate protein concentrations: proteins adsorbed to Alhydrogel, proteins in solution with gold nanoparticles, and proteins encapsulated within polymeric microspheres. Protein concentrations in each of the three protein\u2013particle systems were successfully quantified using a calibration curve created from the absorbance at 280 nm.<\/p>\n<br><div class=\"tagcloud\"><a href=\"https:\/\/www.bihec.com\/olisclarity\/tag\/%e6%b7%b7%e6%b5%8a%e6%ba%b6%e6%b6%b2\/\" class=\"tag-cloud-link tag-link-0 tag-link-position-1\" style=\"font-size: 8pt;\" aria-label=\"\u6df7\u6d4a\u6eb6\u6db2 (1\u4e2a\u9879\u76ee)\">\u6df7\u6d4a\u6eb6\u6db2<\/a>\n<a href=\"https:\/\/www.bihec.com\/olisclarity\/tag\/%e8%9b%8b%e7%99%bd%e8%b4%a8%e6%b5%93%e5%ba%a6\/\" class=\"tag-cloud-link tag-link-1 tag-link-position-2\" style=\"font-size: 8pt;\" aria-label=\"\u86cb\u767d\u8d28\u6d53\u5ea6 (1\u4e2a\u9879\u76ee)\">\u86cb\u767d\u8d28\u6d53\u5ea6<\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>CLARiTY\u5149\u8c31\u4eea\u7528\u4e8e\u76f4\u63a5\u6d4b\u91cf\u6df7\u6d4a\u6eb6\u6db2\u4e2d\u7684\u86cb\u767d\u8d28\u6d53\u5ea6 Label-Free, Direct Measurement of Protein Concentrations in Tu <\/p>\n","protected":false},"author":1,"featured_media":13732,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_vp_format_video_url":"","_vp_image_focal_point":[]},"categories":[1],"tags":[10,9],"_links":{"self":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13731"}],"collection":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/comments?post=13731"}],"version-history":[{"count":0,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13731\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media\/13732"}],"wp:attachment":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media?parent=13731"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/categories?post=13731"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/tags?post=13731"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
